Title:
UNWROUGHT REFRACTORY COMPOSITION, IN PARTICULAR FOR PRODUCING GLASS FURNACE HEARTHS
Document Type and Number:
WIPO Patent Application WO2003043953
Kind Code:
A8
Abstract:
The invention concerns an unwrought refractory composition, in particular for producing glass furnace hearths, characterized in that it comprises a base mixture comprising in wt. %: 1 to 6 % of a hydraulic cement, and 94 to 99 % of particles of at least a refractory material mainly consisting of alumina (Al2O3), zirconia (ZrO2) and silica (SiO2), the fraction of the particles of said base mixture having a size less than 40 µm being distributed in wt. % relative to the weight of said base mixture, as follows: fraction < 0.5 µm: >= 4 %; fraction < 2 µm: >= 5 %; fraction < 10 µm: >= 16 %; fraction < 40 µm : 29-45 %, said refractory composition further comprising, in wt. % relative to the weight of said base mixture : 0.02 to 0.08 % of organic fibers, and 0.075 to 1 % of a surfactant.
